+The `interop_task` allows users to submit tasks containing C++ statements with low-level API calls (e.g. OpenCL Host API entries).
 The command group that encapsulates the task will execute following the usual SYCL dataflow execution rules.
 The functor passed to the `interop_task` takes as input a const reference to a `cl::sycl::codeplay::interop_handle`. The handle can be used to retrieve underlying OpenCL objects relative to the execution of the task.
 
 It is not allowed to allocate new SYCL object inside an `interop_task`.
-It is the user responsibilities to ensure all operations peroformed inside the `interop_task` finished before returning from it.
+It is the user's responsibility to ensure that all operations performed inside the `interop_task` are finished before returning from it.
 
 Although the statements inside the lambda submitted to the `interop_task` are executed on the host, the requirements and actions for the command group are satisied for the device.
 This is the opposite of the `host_handler` vendor extension, where requisites are satisfied for the host since the statements on the lambda submited to the single task are meant to have side effects on the host only.
